Passing arguments to event handlers in WxPerl is something you never have to do :)

Having code outside of subroutines is something you never have to do :) (really shouldn't )

EVT_COMBOBOX ... How is this done?

As documented :) my wxWidgets / wxPerl / wxGlade tutorial, wxperl_usage / wxperl-usage / wxPerl::Usage / Class Method Browser , available methods, method invocation syntax, link to docs 

sub Combobox1action {
    my( $frame, $comboevent ) = @_;
    my $combobox  = $comboevent->GetEventObject;
    my $selection = $comboevent->GetString;
    $frame->SetTitle( "Combo box selected ($selection)" );
}
